CUSTOMS AND BROKERAGE FEES, DUTIES, AND TAXES

For orders that are shipping to destinations outside of the United States (including Canada), you may have to pay duties and taxes to your country's government. This is because you are importing goods from a foreign country into your own country.

C-IN2 does not estimate nor collect these duties and taxes on your behalf. Please contact your country's customs office to obtain an estimate of the duties and taxes, if any, you will have to pay.

We cannot and will not alter, falsify, or in any other way misrepresent or undervalue the declared value of an international shipment. The full amount of the purchased items will be noted on the customs declaration.

In addition to duties and taxes, you may have to pay an additional brokerage fee to either your country's postal system (if your order ships via our International Standard or International Standard Plus shipping methods) or to FedEx (if your order ships via our International Economy and International Priority shipping methods). This fee, which is not estimated nor collected by C-IN2 on your behalf, covers the carrier's cost of expediting the clearance of your shipment through your country's customs process. A typical brokerage fee averages USD 10.00 - 20.00. Check with your local postal office to estimate any brokerage fees, if any, you will have to pay.

If you do not pay duties, taxes, or brokerage fees, then in many cases the parcel will be destroyed by your country's customs office and not sent back to us. In such cases, we will not issue a refund. We can only issue refunds for parcels that are returned to us.

Need more COLORS

Liked the material feels really good. Waistband stays in place all day and the pouch is of good size. Really wish there was more color to buy more.

Trying thongs for the first time.

I've been trying all sorts of mens thongs and this design is pretty good. Looks super sexy on and it's constructed well. Very comfortable, wears well throughout the day. The pouch material is absorbent and durable and the Y-back is comfy and stays in place. Sizing is spot on. The only feedback I would give about this design is that the waistband feels a little plasticy and rough on the skin. A softer choice in waistband material would make this design much better. The pouch is absorbent and a good size, but the material is not very flexible, so my junk gets a bit squished. A softer, more flexible/stretchy material would make this design heaps more comfortable to wear. Overall, a good design, but the pouch and waistband material selection could be improved.

Great Purchase.

True to size. Comfortable to wear all day. Only critique is the waistband could be a bit wider as it rolls sometimes.

Love it very much

I like how the pouch provides just enough support and shows the budge nicely but the highlight is the Y strap that sits on my buttocks and accentuates it.

The best thong on the market

This thong is the most comfortable type of thong I have ever worn. The low rise aspect is perfect under jeans. The waistband sits comfortably and doesn’t move around. The pouch is perfectly shaped with the perfect amount of support. My only critique - Why isn’t this offered in more colors and styles?? Would love to get some Zen thongs or Hand Me Down thongs. Not sure why c-in2 only has this one pair, I’d buy way more if they introduced different style thongs.

Love

This is the first thing I’ve purchased, and honestly I love it. Feels comfortable (after a bit) waistband is like the rest of their bands for the most part, sexy design. If there were more colors I’d buy them too! I also bout my regular size and it turned out just fine :)

Yes. I definitely would buy the product again and again!

These are perfect for almost if not all my needs! Airy, cool, and no worries about underwear lines showing through.
